Michael, I would find that a tempting approach, however, in your first 
paragraph, you state that everything can be executed in an undefined 
order. I assume that means, in theory *and* in practice, that the order 
in which the OutputURIResolver is called is undefined and hence, the 
order of the snippets that you are writing to the same target.

Obviously, by collecting the data before writing it, you can order it by 
means of some sort of identifier of course.
